ARMER'P.' LUKER, or PHILADELPHIA, PENNSYLVANIA, AssreNoR'ro vieronTALKING MACHINE COMPANY, `A CORPORATION F NEW JERSEY 'UPRIGIIT CABINETFOR RADIO AEPARATUS A Application tiled February`20, 1925. Serial No.10,675.

This invention relates to mountings for radio panels, and moreparticularly tothe mounting of radio panels in upright cabinets of thetalking machine type.

Ilt has heretofore been proposed to mount radio panels in cabinets ofthe upright type but for the most part it has been found necessary" tofixedly mount said panels in 'a substantially vertical position. Thenumerous adjustments that must be made to the control members whenoperating` a radio receiving set can only be made with difficulty if thepanel carrying said members is iixedly mounted in a vertical position.Accordingly, an object of the present invention is to provide'novel:means for mountingv a radio panel in an upright cabinet which willovercome the above objections.

Another object or the invention is to provide means whereby a panel maybe moved en teriorly of the cabinet into a convenient operating positionwhen it is desired to adjust the radio control members carried there-` byAnother object is to provide .means for V securely maintaining 'a panelin operating position erteriorly of the cabinet.

A further object of the invention is to provide means whereby no injurywill result to the delicate instruments'carried by said panel in casethe latter should be accidentally moved from its normal operatingposition. T hese and other objects will appear more fully hereinafter inthe Adetailed description.

Twoforms which the inventive idea may assume are shown in theaccompanying drawings, whichdrawings, however, are for thel purpose'ofillustration only and are not to be taken as defining the limits of thein vention, reference being had to tlie appended Y claims for 'thispurpose.

In the drawings, i

Fig. 1 `is a sectional side elevation of a 45 cabinet embodying thepresent invention;

F ig. 2 is ar side elevation, partially in section and with parts brokenaway, illustrating another form of the inventive idea; and

50 Figs. 3 and are sectional views taken on line 3--3 ofFig. 2, and line4 4 of Fig. 3,

respectively.

Referring to the drawings wherein like reference characters refer 'tolike parts `throughout the several views, 1 is a talking the sides ofthe 4cabinet 1 and may be pro-V vided with upper and lower walls 10 and11 respectively, contains a panel 12 of any suitable character, size,and material which is secured to the upper wall l0 in such a manner thatthe panel may be swung to a substantially horizontal positionexterior-'ly of the cabinet. ln the form shown, the connection'betweenthe panel l2 and wall 10 comprises a pair of, brackets 13 secured toeach side of the panel adjacent the upper end thereof in any suitablemanner, as by means of screws. Each of the brackets is provided with a.forwardly extending portion adapted to receive a pin 14: which engagesand is retained inoperative position by adownwardly extendingbraclretmember 15 secured to the lower surface of wall 10. A spring latch 16 ofany suitable type is mounted in any desired manner in the lower wall 11for yieldingly retaining the panel 12 in upright position, in thecompartment 9, whenvthe same is not in use. i y

The panel 12 is particularly adapted as a mounting for elements of aradio receiver, the control members for which are illustrated by themembers 17, 18 and 19. lit will be understood, however, that thisshowing is idiagrammatlc only and that any suitable control means may beemployed. In order that "the adjustments necessary in the operation lofthe radio receivingA set may be made with facility, 1t is' desirablethatthe panel carrying l deslred, however, only'one of said arms may lmeans for retaining the panel in a horizontal,

operative position comprise a pair of jointed arms, onefor each side ofthe panel 12.. If

I vbe employed. Preferably, each arm comprises an upper link 21 whichlis pivotally connected at its upper end to a bracket 22 securedvto t-herear .or lower faceA of the panel 12, and at its lower end istpivoted asat 23 to a lower link 24. The link 24 is pivotally connected at itslowerend to a bracket 25v f which is secured to the upper surface of thezov vtion 23 between the links is so located'that the operationof theradio receiving set may compartment wall 11. The pivotal connecthelatter overlap for a suitable distance, and on the upper edge of theoverlapping portion of the lower link 24 there is preferably provided alaterally projecting lug or stop member 26 which prevents outwardbreaking of the joint formed at 23. The electrical units, such as drycells, required in connection with be positioned in compartment 9between the rear wall-of the cabinet 1 and the panel 12 asdiagrammatically' illustrated at 27 and 28.. Preferably, a door 29, or apair of doors, provided with hinges 30,' are secured to the cabinet 1 ina position to close the compartment 9 occupied by the panel when thelatthe dotted line showin catch device 16 resilient y lockin the panel.in said position. When so house the swinging door or`doors 29 are closedto prevent ter is housed therein and not in use. .The necessaryconnections to antenna or ground may be V.madethrough one or moresuitable openings-such as A31 formed inthe lower wall 11.`

Normall the panel 12' and the instruments carried thereby are housedwithin the compartment 9' with the panel ina-substan tially verticalposition, as is indicated by in Figure 1, the

dust or moisture from damaging the delicate instruments carried Vby thepanel. When it is desired to .operatethe radio set, the door or doors 29are opened and the panel 1 2 is swung outwardly about the pivots 14 toa'substantiallyv horizontal position. This movement of the panel resultsin bringing the' links 21'and 24 of the supporting arms intoalinement toconstitute a rigid support -for the panel, whereby the same is held in aposition which facilitates the actuation of the control members. 17, 18and 19; If the I joint 23 is accidentally broken when the panel i'sinthe vhorizontal position, the' panel will swing downwardly but will.not move to position due to the centric mounting -are so formed that thethe instruments carried by the panel.

of said pivots. Accidental damage to the delicate lnstrumentscarriedbythe panel is thus avoided.

Referring to4 Figures 2, 3 and 4 illustrating anothery embodiment of thepresent invention, the panel 12 is shown slidably mounted in thecompartment 9a of the cabinet 1.- vSecured to the op osite side edges of the panel 12 are side mem ers 32 which are substantial- 1y triangularin shape and which are provided on their lower outer edges withhorizontal ribs 33 that slidably engage the. sides of grooves 34 formedin a supporting member 35 secured to the upper surface of lower wall 11.The front edges of the side members 32 faci itates the adjustment of thecontrol eleconstitute an inclined sup ort for the pane 12 whichinclinationments 17, 18 and 19. When not in use, the v panel 12 andsupporting members 32 therefor, are moved to a position within the com-'partment 9* as illustrated in dotted lines in.

Figure 2, and the door or doors 29 are closed to prevent dirt ormoisture from dama 'ng en it is desired to operate the radio receiver,the doors 29 are opened and the panel 12 is moved to operating itionexteriorly of the cabinet by means o the knob 20, said panel beingsecurely supported in this vposition by means of the tongue and grooveconnection described.

It will be seen that there i's provided. a novel mounting for theinstrument anel .of a radio receiving set in an upright pllionographcabinet, which panelV maybe moved exteriorly of the cabinet and securelyheld in operating position. Closure `means are provided for the panelcompartment to prevent fo'reign matter from destroying the ments oftheinvention have been illustrated.

and described with considerable particularity, it will be understood`that the invention is not limited thereto, but that changes 'may be'made in the details of construction .within the limits of the appendedclaims.

1. In combination with a'talking machine cabinet having acompartmenttherein, a

panel carrying radio control members in said proper functioning of thedevice. The de compartment, said panel normally occupying averticalposition closing said compartment.,y

means pivotally connecting said panel to said cabinet, the pivot axis.'being located at a distance in front ofsaid panel, and means forvA'1,745,3oe
